for srivastava paper, equation (25) is not clear about a value but for the 2006 w-l papers (25) they preted a value of a which does nor match the result... a=50nm (about bohr radius), but the computation seemes to use around a femtometer (proton size). anyway now all the papers, seems coherent if a=~1fm (the charge size of a proton)
anyway, this does not seems to hurt critics, who moans on other subjects ( http://newenergytimes.com/v2/sr/WL/critique/GrabiakCritique-Widom-LarsenFeb4-2010.pdf...) 2012/1/31 Giovanni Santostasi <gsantost...@gmail.com> > I have a PhD in Physics even if this is not my field, I'm trying to learn > more about it.
